Why compress a PDF before sharing?

Large PDFs are slow to email, awkward to upload, and frustrating on mobile. Compression reduces file size so proposals, brochures, menus, guides, and reports open faster.

Compression is especially useful before creating a QR code or embedding a PDF on a website, because smaller files load more reliably for visitors.

Compression settings

  • Balanced quality works well for most business PDFs.
  • Smallest file is best for email and mobile sharing.
  • Higher quality keeps more detail for design-heavy PDFs.
  • Host the compressed PDF to keep one permanent share link.

PDF compression FAQ

Will compression reduce every PDF?

No. Some PDFs are already optimized. If the compressed output is larger, PDFHost keeps the original-size result instead.

How long is the compressed file available?

The free compressed download is temporary. Create an account to host the PDF permanently.

Can I share the compressed PDF online?

Yes. After compression, use PDFHost to create a permanent link, QR code, embed code, and analytics dashboard.
